Darnall said they expect to file the paperwork to have the case moved to circuit court within the week, with a hearing to be held at a later date.

Circa's affiliate FOX 17 News spoke with Marshall County Attorney Jeff Edwards, who explained the request for the case to be moved to circuit court means they aim to have the teen charged as an adult.

"Normally, a juveniles's case stays in juvenile court. But if the charge is a Class A or B felony and the juvenile is 14-years-old or older, then it qualifies them to be treated as an adult," Edwards says.

"In this case, the crime is so heinous a hearing in juvenile court won't satisfy punishment," Edwards says.

For a Class A felony in the state of Kentucky, the punishment is 20 years-to-life. Edwards says although Kentucky still has the death penalty, the teen will not be eligible for the punishment due to his age.

During his statement, Darnall also praised teachers, staff, and administrators of the school, saying "we commend you for your heroic actions in the face of these events. He also praised first responders, saying their professionalism was "beyond reproach" and made a plea to families affected to contact him with any needs.

"If you need anything, please call me. We are gonna help you in any possible way we can, you are not alone," Darnall said.
